- (a) Field of the Invention
- The embodiments of the present invention relate to a plasma display panel in a plasma display device, and more particularly, to a plasma display panel in a plasma display device that is capable of effectively blocking a path of noise around an exhaust port and an exhaust tube.
- (b) Discussion of the Related Art
- Generally, a plasma display panel (PDP) is formed from a front plate and a rear plate that are sealed to one another to hold a discharge gas inside. The front plate includes a front substrate, display electrodes formed on a rear surface of the front substrate, a dielectric layer covering the display electrodes, and a protective layer formed on the dielectric layer. The rear plate includes a rear substrate, address electrodes formed on a front surface of the rear substrate so as to intersect the display electrodes, a dielectric layer covering the address electrodes, barrier ribs formed on the dielectric layer to divide discharge cells and a phosphor layer formed in the discharge cells.
- The PDP is driven by sequentially generating an address discharge, a sustain discharge and a reset discharge. Specifically, when a sustain pulse is applied to display electrodes, an electrical field is formed between the display electrodes and the address electrodes in the discharge cells. The discharge gas is excited to a high-energy plasma state by the electrical field and is then stabilized to a low energy level to generate ultraviolet rays. The ultraviolet rays excite the phosphor layer to a higher energy level. The phosphor layer is then stabilized to a low energy level to radiate visible rays. As a result, a desired image can be generated.
- The above-mentioned PDP has an exhaust port and an exhaust tube located on one side of the rear substrate. The exhaust port and the exhaust tube are indispensable to the process of evacuating air from the sealed area inside of the front plate and the rear plate and to the process of completing the seal of the plates after injecting discharge gas into the interior space. The exhaust port and the exhaust tube secure a passage in the PDP through a dummy region, that is, a terminal connecting region formed between a display region that displays images and an interconnection region that connects electrode terminals to a connector.
- When a PDP having the above-mentioned structure is driven, a natural frequency of the plasma display panel resonates with the frequency of a driving signal that is applied to the display electrodes from a driving circuit. This resonance results in the generation of noise. The noise is amplified by the exhaust port and the exhaust tube that are formed on one side of the rear substrate.
- Embodiments of the invention provide a plasma display panel and a plasma display device capable of effectively blocking the path of noise around an exhaust port and an exhaust tube that are formed on one side of a rear plate.
- In one embodiment of the invention, a plasma display panel includes a first and a second plate that are sealed to each other to form discharge cells between the plates. The discharge cells can generate images through gas discharge. The plasma display panel also includes an exhaust port that is formed in the vicinity of an edge of the first plate. The exhaust port is a part of a path connected to the discharge cells. An exhaust tube is formed on the outside of the first plate and is connected to the discharge cells through the exhaust port provided in the first plate. A pad is disposed on the first plate around the exhaust port and the exhaust tube.
- In another embodiment of the invention, a plasma display panel may include a chassis base that is attached to the first plate having the pad by a double-sided tape. In this embodiment, the pad contacts opposing surfaces of the first plate and the chassis base. The pad may contact the outer circumference of the exhaust tube or be interposed between the opposing surfaces of the first plate and the chassis base to directly absorb noise and vibration generated around the exhaust port and the exhaust tube. The pad may be formed separately from the double-sided tape that attaches the first plate to the chassis base or formed as an extension of the double-sided tape. The pad may be made of silicon or composed of an adhesive tape or foam adhesive tape to effectively absorb the noise and vibration.

FIG. 1 is an exploded perspective view of a plasma display device with a plasma display panel and a chassis base according to an embodiment of the present invention, andFIG. 2 is a partially exploded perspective view of the plasma display panel according to the embodiment of the invention. - Referring to
FIGS. 1 and 2 , the plasma display panel (“PDP”) according to an embodiment of the invention includesdischarge cells 19 that generate images by using gas discharge therein. Thedischarge cells 19 are formed by sealing a first plate 100 (hereinafter, referred to as a ‘rear plate’) to a second plate 200 (hereinafter, referred to as a ‘front plate’). The height of thedischarge cells 19 is considerably smaller than those of therear plate 100 and thefront plate 200. Therefore, inFIG. 1 , it appears as though arear substrate 1 and afront substrate 2 are directly sealed to each other. - The PDP includes a set of sustain
electrodes 3 and scan electrodes 5 that serve as display electrodes. The display electrodes are formed on an inner surface of thefront substrate 2 that forms thefront plate 200.Address electrodes 9 are formed on an inner surface of therear substrate 1 that forms therear plate 100. Thesustain electrodes 3 and the scan electrodes 5 are covered with a laminate structure including adielectric layer 11 and aprotective layer 13. Theaddress electrodes 9 formed on the inner surface of therear substrate 1 are covered with adielectric layer 15.Barrier ribs 17 are formed on thedielectric layer 15 to define thedischarge cells 19 and aphosphor layer 21 is formed in thedischarge cells 19. Mixed inert gas, such as Ne or Xe, is charged in thedischarge cells 19. The display electrodes and theaddress electrodes 9 intersect each other with thedischarge cells 19 interposed therebetween to allow for the selection of adischarge cell 19. Thebarrier ribs 17 extend in one direction (Y-axis direction) in strips. Alternatively, thebarrier ribs 17 may be formed in a matrix with ribs extending in two intersecting directions, such as X-axis and Y-axis directions. - Heat radiating
sheets 27 and double-sidedadhesive tapes 29 are provided on therear substrate 1 of the PDP. The PDP is attached to thechassis base 31 to form the plasma display device. In this plasma display device, theheat radiating sheets 27 transmit the heat generated when the PDP is driven to thechassis base 31. Therear substrate 1 of the PDP is attached to thechassis base 31 by the double-sided adhesive 29 so that theheat radiating sheets 27 are positioned between therear substrate 1 and thechassis base 31. - When the PDP is driven, address discharges are initiated by an address pulse applied to the
address electrodes 9. A scan pulse is applied to the scan electrodes 5 during an address period to select adischarge cell 19 to be turned on. During a sustain period, a sustain discharge is initiated by positive and negative sustain pulses which are alternately applied to the scan electrodes 5 and thesustain electrodes 3, which result in the generation of images. - During the manufacture of the plasma display panel, air remains in the
discharge cells 19 formed between thefront substrate 2 and therear substrate 1 that are sealed to each other. This air is evacuated from inside of thedischarge cells 19, then the discharge gas is filled therein and finally the filling path is sealed. As shown inFIGS. 3 and 4 , the PDP has anexhaust port 23 on one side of therear plate 100, more specifically on one side of therear substrate 1, and anexhaust tube 25 formed around theexhaust port 23. - The peripheries of the
front substrate 2 and therear substrate 1 are sealed to one another by aglass frit 101 and theexhaust port 23 serves as a passage for connecting a discharge space, that is, thedischarge cells 19 formed between thefront substrate 2 and therear substrate 1, to the outside. Theexhaust tube 25 is connected to a portion of theexhaust port 23 that is positioned on the surface of therear substrate 1 facing thechassis base 31 and protrudes outwardly. When evacuating air and injecting the gas, the inside of the plasma display panel communicates with the outside through theexhaust tube 25. After gas injection is completed, theexhaust tube 25 is sealed such that the inside and the outside of the PDP are isolated from each other. Theexhaust tube 25 projects from the surface of therear substrate 1. Theexhaust tube 25 may be located in a through-hole 31 a formed at the periphery near an edge of thechassis base 31. Therear substrate 1 and thechassis base 31 may be attached to each other because theexhaust tube 25 projects through the through-hole 31 a to the outside. - The
exhaust port 23 and theexhaust tube 25 are formed straight and in a direction (z-axis direction) of the thickness of therear substrate 1. Theexhaust port 23 and theexhaust tube 25 may have various cross-sectional shapes. In one embodiment, the sectional shapes of theexhaust port 23 and theexhaust tube 25 may be circles. By forming theexhaust port 23 with a circular shape, stress is concentrated on theexhaust port 23 that is due to external forces acting on therear substrate 1. Using the circular shape, it is possible to effectively prevent the breakdown of therear substrate 1. By forming theexhaust tube 25 in a circular shape, it is further possible to effectively withstand the pressure applied when gas is evacuated or injected. - When the plasma display panel is driven, the natural frequency of the plasma display panel resonates with the driving frequency. As a result, on the side of the PDP, a noise or vibration is caused by the resonance. At the time of the resonance, the space inside the
exhaust port 23 and theexhaust tube 25 serves as a resonator to amplify the noise or vibration generated from the side of the plasma display panel. In order to absorb the noise or vibration, apad 33 is provided in a portion of therear substrate 1 around theexhaust port 23 and theexhaust tube 25. - The
pad 33 may be formed in various structures or made of various materials that are capable of effectively absorbing the vibration and the noise generated inside or around theexhaust port 23 and theexhaust tube 25 when the PDP is driven. Thispad 33 functions to interrupt the transmitting path of the noise rather than to eliminate the noise source from the plasma display panel. Thepad 33 may be attached to the periphery of theexhaust port 23 without contacting the outer circumference of theexhaust tube 25. In another embodiment, thepad 33 may be attached to the periphery of theexhaust port 23 while directly contacting the outer circumference of theexhaust tube 25. The vibration caused by the resonance generated in theexhaust port 23 and theexhaust tube 25 can be effectively absorbed improving the absorption performance of noise and vibration for the side of the plasma display panel. - The
pad 33 may be attached to only a portion of therear substrate 1 at the periphery of theexhaust port 23 or may be interposed between opposing surfaces of therear substrate 1 and thechassis base 31 to contact the opposing surfaces thereof, as shown inFIG. 4 . As mentioned above, as thepad 33 contacts the opposing surfaces of therear substrate 1 and thechassis base 31, some of the noise and vibration generated from the plasma display panel are absorbed by thepad 33, the remainder of the noise and vibration are transmitted to thechassis base 31. This structure improves absorption performance for noise and vibration. Thepad 33 has the same thickness as that of the double-sided tape 29 so that therear substrate 1 and thechassis base 31 are evenly bonded to each other without being loose, as seen from the side thereof. - As shown in
FIG. 4 , thepad 33 may be formed separately from the double-sided tape 29 that attaches therear substrate 1 of the PDP to thechassis base 31. In the case that the double-sided tape 29 merely attaches therear substrate 1 of the plasma display panel to thechassis base 31, thepad 33 which is capable of absorbing the vibration or the noise can be made of a different material from the double-sided tape 29 regardless of the material or structure of the double-sided tape 29. Therefore, the flexibility of the design is further improved. - Moreover, as shown in
FIG. 5 , apad 332 may be formed as an extension of a double-sided tape 292 that attaches therear substrate 1 and thechassis base 31. In this embodiment, thepad 332 is integrally formed with the double-sided tape 292. When using the integrated structure mentioned above, because thepad 332 is not formed separately from the double-sidedadhesive tape 292, it is possible to reduce the number of processes required to form thepad 332. In this embodiment, the extension may be removable from theexhaust tube 25 or the extension may contact the outer circumference of theexhaust tube 25 in order to absorb the noise and vibration. - The
pads pads adhesive tapes - As mentioned above, according to one embodiment, an exhaust port is provided along the edge of the one side of the rear plate and an exhaust tube is connected to the exhaust port. In addition, a pad or an adhesive tape is provided around the exhaust port and the exhaust tube. In this way, the noise and vibration around the exhaust port and the exhaust tube can be absorbed and a path through which the noise is transmitted from the exhaust port and the exhaust tube to the entire plasma display panel can be effectively blocked. In one embodiment, by forming the pad with silicon or a foam adhesive tape, it is possible to effectively absorb the noise and vibration around the exhaust port and the exhaust tube.
- Although various embodiments of the present invention have been shown and described, it should be appreciated by those skilled in the art that changes may be made to the disclosed embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
